engineering recuitment GATE ECE 2023-24 Test Series Analog Electronics Bipolar Junction Transistors Frequency Response
Consider the common emitter amplifier shown below with the following circuit parameters:
β = 100, gm = 0.3861 A/V, r0 = ∞, rx = 259 Ω, Rs = 1 kΩ, RB = 93 kΩ, RC = 250 Ω, RL = 1 kΩ, C1 = ∞ and C2 = 4.7 μF
The lower cut-off frequency due to C2 is
1
33.9 Hz
2
27.1 Hz
3
13.6 Hz
4
16.9 Hz
